I used a Levinson[0] for about a year and then switched to a Kyria[1] in August. My Kyria is fully wireless by using two nice!nano microcontrollers and ZMK firmware. I absolutely love small keyboards like this. It takes a couple days/weeks to get used to the positions of everything, but once you do it's amazing. Not having to move your hands/wrists constantly is a game changer. I've ordered PCB's for a Ferris Sweep[2] and plan on building it soon.
